Definitions
- the subject invention relates to needle shields for hypodermic needles, blood collection needles, catheter needles and other medical implements to help prevent accidental needle sticks.
- Some prior art hypodermic syringes include a shield telescoped around the needle cannula rather than around the syringe barrel. This type of shield is advanced distally after the hypodermic syringe has been used. This prior art assembly with the shield telescoped on the needle hub requires a needle which is approximately twice as long as the needle required for the procedure because needle length is taken up by the telescoping elements before use. These devices too, unless spring loaded, require two hands for shielding.
- Some prior art safety shields have relied on coil springs coaxially positioned around the needle cannula to automatically move the shield.
- the shield may be locked in the proximal position with the coil spring compressed. Unlocking the shield causes the coil spring to urge the shield distally into the shielded position.
- it is generally undesirable to provide an apparatus which is usually made of thermoplastic components to be stored for a considerable period of time under the stress of a compressed coil spring. The stored energy can cause the plastic parts to deform, and may alter the performance of the shield.
- a self-contained needle shield assembly wherein the shield can be positioned using a one-handed procedure and the shield can be selectively locked, to prevent further use, or intentionally unlocked to allow a second use of the needle such as when the needle is used both for filling the syringe and for delivering the medication.
- a self-contained shielded needle cannula that provides a clear indication to the user that the shield is safely and securely locked over the cannula and that the needle assembly can be disposed of without further risk of needle sticks.
- EP-A 555,974 describes a safety needle device with safety color indicator means for visibly indicating that a needle guard is not locked in an extended, needle-guarding position, and obscurement means on the guard to change the appearance or obscure the safety indicator means when the needle guard is in the locked extended position.
- a needle shield assembly of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough.
- a hub having a proximal end for connecting to a medical instrument and a distal end connected to the proximal end of the needle cannula is provided.
- a base member is connected to the hub.
- An elongate needle shield includes a proximal end hingedly connected to the base member, a distal end and a longitudinal axis therebetween.
- the needle shield includes a longitudinal opening therein.
- the needle shield is capable of rotating from a first position exposing at least the distal end of the needle cannula to a second position wherein the needle cannula is within the longitudinal opening of the needle shield, and back to the first position.
- a sleeve having a longitudinal slot is rotatably connected to the needle shield. The sleeve is capable of rotating about the needle shield to an open position where the longitudinal slot in the sleeve and the longitudinal opening in the needle shield are sufficiently aligned to allow passage of the needle cannula so that the needle shield can be rotated from the first position to the second position and back to the first position, if desired.
- the sleeve is rotatable about the needle shield, to a position which blocks the longitudinal opening of the needle shield.
- Color safety indicator means for visually indicating the sleeve is rotated to a position which blocks the longitudinal opening of the needle shield is provided including a color segment on the needle shield which is visible through the sleeve when the sleeve is rotated to a position which blocks the longitudinal opening.
- a needle shield assembly having safety indication features such as needle shield assembly 20 a needle cannula 21 having a proximal end 22 a distal end 23 and a lumen 25 therethrough.
- the distal end of the needle cannula includes a sharpened tip 26.
- a hub 28 includes a proximal end 29 and a distal end 31 connected to proximal end 22 of the needle cannula.
- a base member 32 is connected to the hub. There are many ways to join the base member to the hub such as through an interference fit, adhesives, ultrasonic welding and the like. It may be desirable in high volume production to integrally injection mold the hub and the base member as a one-piece unit thereby eliminating the assembly step.
- An elongate needle shield 35 includes a proximal end 37 hingedly connected to base member 32.
- the hinge connection is accomplished by hinge holes 34 in spaced parallel arms 33 of the base member wherein opposed circular hinge pins 38 on the elongate needle shield engage hinge holes 34 to allow the needle shield to rotate about an axis which is transverse to the longitudinal axis of the needle cannula.
- Elongate needle shield 35 also includes a distal end 39.
- a longitudinal axis 40 extends between the proximal and distal end of the needle shield.
- the needle shield includes longitudinal opening 41 which ends at the distal end of the needle shield at end wall 43.
- the longitudinal opening allows the needle shield to rotate about the base member from a first position exposing the distal end of the needle cannula to a second position wherein said needle cannula is within said longitudinal opening of the needle shield, as best illustrated in Figs. 3 and 4.
- the first position of the needle shield, exposing the distal end of the needle is preferably at approximately 180° from the second position, as illustrated in Fig. 1.
- first position at any angle between several degrees and 180° which exposes the distal end of the cannula for its intended purpose, such as, approximately 90° from the second position, so that in the first position the longitudinal axis of the needle shield is approximately perpendicular to the longitudinal axis of the needle cannula.
- 180° first position is preferred because it is less obtrusive and less likely to interfere with the injection process.
- a sleeve 46 having a longitudinal slot 47 is rotatably connected to needle shield 35.
- Sleeve 46 is capable of rotating from an open position wherein the longitudinal slot 47 and the longitudinal opening 41 are sufficiently aligned to allow the passage of the needle cannula so that the needle shield can be rotated from the first position to the second position, as best illustrated in Fig. 4.
- Sleeve 46 is rotatable to a position which blocks longitudinal opening 41 of the needle shield, as best illustrated in Fig. 6, so that the needle shield can be locked or secured trapping the needle cannula within the shield.
- a safety indicator means is provided for visually indicating when sleeve 46 is rotated to a position which blocks longitudinal opening 41 of needle shield 35.
- the sleeve is mounted on the exterior of the needle shield and a color segment 51 is deposited on the exterior of the needle shield.
- the color segment can also be molded into the shield, such as by two-part molding, or the entire shield can be molded in color.
- color segment 51 be a bright color which is easily visualized from a short distance such as green, which usually indicates safety, or white, black or blue. Other colors are within the purview of the present invention.
- longitudinal slot 47 is positioned over color segment 51 on the needle shield projecting to the user a bright colored longitudinal stripe which indicates that the needle cannula is securely contained within the needle shield and rotation of the needle shield will not re-expose the needle to the user.
- the color indicating means indicates that if the user attempts to rotate the needle shield the needle will be bent while still remaining trapped within the needle shield.
- a user who intends to re-expose the needle cannula will rotated the sleeve to the position which exposes longitudinal opening 41 so that the needle shield can be safety rotated to re-expose the needle without bending or damaging the needle.
- the longitudinal slot in the sleeve for allowing the needle shield to rotate and also for exposing the color segment.
- another aperture can be placed in the sleeve for the same purpose.
- the sleeve can be manufactured to have a transparent segment so that when the sleeve is rotated to the position which blocks the longitudinal opening of the needle shield the transparent section of the sleeve will be over the color segment.
- the embodiment shown in Figs. 1-6 is merely preferred because of its simplicity and ease of manufacture. It is also within the purview of the present invention to have the sleeve inside the needle shield so that the safety indicator would have to be on the sleeve and the aperture or transparent section would have to be on the needle shield. This embodiment is not preferred because the most practical way to rotate the shield would be having the sleeve project beyond the distal end of the needle, and it is preferred to keep the operator's fingers away from the distal end of the needle.
- means for limiting rotational movement includes a projection 50 on proximal end 45 of sleeve 46 and a protuberance 44 on proximal end 37 of needle shield 35.
- the color segment is conveniently located within the longitudinal slot of the sleeve and rotation cannot proceed too far, and the user is not forced to rotate the sleeve back and forth to find the safety indicator means. Accordingly, rotating the sleeve to the position of safe containment of the needle cannula is accompanied by the tactile sensation of the projection abutting against the protuberance, and the visual sensation of observing the color segment. At this point the user knows that the needle is safety shielded and cannot be accidentally re-exposed.
- the projection and the protuberance so that there is a reversible snap-fit type engagement which will provide a tactile sensation when the projection and the protuberance engage and also provide a resisting force which will require the user to apply a more deliberate force to re-expose the longitudinal opening of the needle shield.
- This tactile sensation could also be provided by a projection on the sleeve or needle shield and a complimentary cavity in the needle shield or sleeve so that at the position where the longitudinal opening of the needle shield is covered and the color segment is visible, the projection falls into the cavity making an audible sound.
- a more aggressively configured projection and cavity could be used to produce a needle shield wherein the sleeve is permanently locked the first time it is rotated to a position in which it covers the longitudinal opening of the needle shield and exposes the color segment.
- this structure is desirable to avoid a second, unwanted, use of the needle.
- means for releasably retaining the needle shield in the second position comprises a projection 52 on needle shield 35 and a recess 53 on base member 32 which is sized and shaped to frictionally engage the projection on the base member when the needle shield is rotated into the second position.
- recess 53 is narrower at its opening so that the projection snaps into the recess to releasably hold the needle shield in the second position.
- the retention force is intended to be minimal, to avoid accidental and not intentional rotation of the needle shield.
- the projection and slot structure illustrated is merely representative of these many ways.
- the projection and the slot can be reversed, the parallel arms 33 of the based member contain inwardly directed projections which snap over the needle shield when it rotates into the second position and various other structures providing frictional or slight interference engagement can be provided to achieve this result.
- needle shield assembly 20 is connected to a hypodermic syringe 56 comprising a syringe barrel 57 having a distal end 58, a proximal end 59 and a circular side wall 61 therebetween defining a chamber 62 for retaining fluid.
- the distal end of the syringe barrel is connected to the hub so that lumen 25 of the needle cannula is in fluid communication with chamber 62 of the syringe barrel.
- distal end 58 of the syringe barrel includes an elongate tip having a passageway therethrough which provides the fluid path between the lumen of the cannula and the chamber.
- the distal end of the syringe barrel also includes a locking luer type collar 63 concentrically surrounding the tip. The luer collar has an array of internal threads which may engage the needle hub to hold it securely to the syringe barrel.
- Fig. 7 illustrates an alternative embodiment of the present invention.
- This embodiment is substantially similar in function to the embodiment of Figs. 1-6 except for safety indicator means.
- alternative needle shield assembly 67 includes needle cannula 21 and elongate needle shield 35 having longitudinal opening 41 as in the embodiment of Figs. 1-6.
- a sleeve 68 having a longitudinal slot 69 is rotatably connected to the exterior of needle shield 35.
- Sleeve 68 is capable of rotating about said needle shield to an open position wherein longitudinal slot 69 and longitudinal opening 41 are sufficiently aligned to allow the passage of the needle cannula so that the needle shield can be rotated around the base member to a second position where the needle cannula can enter the longitudinal slot of the needle shield.
- sleeve can then be rotated to a position, illustrated in Fig. 7, which blocks longitudinal opening 41 of the needle shield.
- a larger color segment 71 is deposit on the exterior of needle shield 35.
- sleeve 68 includes transparent window 70.
- transparent window 70 is positioned over color segment 71 on the needle shield, projecting to the user a bright colored stripe which indicates the needle assembly is securely contained within the needle shield and that the longitudinal opening is covered by the sleeve.
- the transparent window can be separately made and attached to an aperture in the sleeve, or it can be molded therein by a co-injection process or a co-extrusion process of transparent or translucent materials.
- the transparent window allows a larger safety indicator without providing another segment on the sleeve for re-exposing the needle.
- Figs. 8-9 illustrate another alternative embodiment of the present invention.
- Alternative needle assembly 80 functions substantially similarly to the embodiment of Figs. 1-6 with the exception of the structure hingedly connecting the base member to the elongate needle shield and means for releasably retaining the needle shield in the second needle protecting position.
- needle shield assembly 80 includes needle cannula 21 having a proximal end 22, and a distal end 23.
- a hub 28 having a proximal end 22 for connecting to a medical instrument and a distal end 31 connected to proximal end 32 of the needle cannula.
- a base member 81 is connected to the hub.
- An elongate needle shield 83 includes proximal end 84 hingedly connected to base member 81 through living hinge 85.
- needle shield 83 includes a longitudinal opening therein so that the needle shield is capable of rotating about base member 81 through living hinge 85 from a first position exposing the distal end of the needle cannula, as illustrated in Fig. 8, to a second position wherein the needle cannula is within the longitudinal opening of the needle shield.
- the embodiment of Figs. 8-9 also includes means for releasably retaining the needle shield in the second needle protecting position so that a certain amount of force is required to rotate the needle shield out of this position.
- means for releasably retaining the needle shield in a second position comprises projections 87 on parallel arms 86 of base member 81 forming a recess 89.
- Needle shield 83 includes opposed protuberances 88 having a cross-sectional width larger than the distance between projections 87 on the base member. Accordingly, when the needle shield is rotated into the second needle enclosing position opposing protuberances 88 on the needle shield frictionally engage and pass over projections 87 on the base member, in a snap fit action, to releasably retain the needle shield in a second needle enclosing position. Additional force, over that required to rotate the needle shield on hinge 85, is required to move the needle shield from the second needle enclosing position to a position which exposes the needle cannula because the interference of projections 87 and protuberances 88 must be overcome.
- the present invention provides a simple, straight-forward, reliable, easily fabricated needle shield assembly wherein the needle shield can be moved to a needle protecting position using a one-handed procedure and the shield can be selectively locked, through rotation of the sleeve, to prevent further use, or it can be intentionally unlocked to allow a second use of the needle, such as when the needle is being used both for filling the syringe and for delivering the medication.
- the present invention also provides a clear indication to the user that the shield is safety and securely locked over the needle cannula and that the needle assembly can be disposed of without further risk of needle sticks.
